Communication Interface Specifications
You can use the USB port or RS-232C/422 connector of the Controller to perform serial communication with
external devices such as a personal computer or programmable controller.
Serial communication functions in the RUN mode. Communication cannot be performed in the ADJ or MENU
modes.
<USB>
This interface allows Full speed (12 Mbps) communications compliant with USB2.0 with a PC equipped with
the same USB interface.
<RS-232C/422>
This interface allows data communications compliant with the EIA RS-232C/422 standards up to a maximum
speed of 115200 bps.
For details on how to set the communication specifications, refer to the User's Manual.

Connection
Connecting a PC
<USB>
Use a USB cable (ZFX-XUSB) to connect the Controller to the
PC.
• When connecting the PC, refer to the Instruction Manual for the PC.
• Attach the ferrite cores supplied to both ends of the USB cable.
<Ethernet>
Use a commercially available LAN cable to connect the Controller
to the PC.
There are two ways of making the LAN connection to the PC,
directly to the PC or via a hub.
The following communications are not possible:
• Communications with the Controller from outside the LAN
• Communications between the Controller and two or more PCs
• Communications between Controllers
• Communications between the Controller and the PLC
Installation of the USB driver is necessary only when connecting an external device to the USB interface for the first
time.
For the USB driver, please contact your OMRON representative.

• 1:1 Connection
When connecting the Controller directory to the PC, use a 10BASE-T or 100BASE-TX cross cable (Category 5
or higher). Limit the cable length to 30 m.
Example: A measurement command is input and the result is acquired.
• 1:N Connection
When connecting two or more Controllers to one PC via a hub, use a 10BASE-T or 100BASE-TX straight cable
(Category 5 or higher). Also, limit the cable lengths between the PC and the hub, and the Controllers and the
hub to 30 m, respectively. Be sure to set unique IP addresses to each Controller. Do not set duplicate IP
addresses to Controllers.
Example:
If communications software for a TELNET
connection is activated on the PC to access the
Controller, the Controller will automatically switch to
the Ethernet connection.
The parallel interface's ENABLE signal will be OFF during measurement.
To end the Ethernet connection, input the
EXIT command.

Connecting a PLC
Use the exclusive RS-232C cable (ZFX-XPT2A) / RS-422 cable
(ZFX-XPT2B) to connect the Controller to a PLC.
When connecting to a PLC, refer to the Instruction Manual for the
PLC.

Configuration of Measurement Value Data
The following explains the output format of measurement values.
To output measurement values by serial communication, the following items must be set.
For detailed settings, refer to the User's Manual.
ASCII Format
Up to 32 results are output as a data structure of fixed length of up to 12 characters including the sign.
Output content
Set the output content as an expression.
Set the output content at [Setup] - [Support] - [Calculation] - [Data].
Output destination
Specify [RS-232C/422] or [USB] at [System] - [Output] - [Data output].
Output format
Set the output format at [System] - [Output] - [Serial output].
Sign The sign of the measurement value is stored. Plus: 0/Minus: -
Number of digits of integer section "0" is inserted in spaces in the integer section and digits past the decimal
point.
When a value is greater than the preset number of digits, all digits other
than the sign digit become "9".
Output range: -9999999.999 to 09999999.999

Binary Format
The value obtained by multiplying the measurement value by 1000 is output continuously as four bytes per
single data item. Minus values are output as 2's complement. Up to 32 results can be output.
The binary format differs from the ASCII format in that data separators, such as field separator or record
separator, do not exist.
Output range: -2147483.648 to 2147483.647
• A value obtained by multiplying by 1000 also is output as the judgment result (JG).
OK: 0
NG: -1000 (-1 x 1000)
• When the measurement value is less than -2147483.648, "-2147483.648" is output.
When the measurement value is greater than 2147483.647, "2147483.647" is output.
